"Lance has been such a strong advocate for marriage equality on the show, it was about time he put a ring on it," Drew Pokorny, writer and co-host of Dirty Pop with Lance Bass, tells omg!.

"Some of his closest friends from Mississippi came to New Orleans to celebrate with Lance and Michael this weekend," Drew continued. "A bunch of his L.A. friends are here too. So it's been an all out love fest! Everyone is so happy for them."

This has been quite the week for Bass!

Lance reunited with *NSync at the MTV Video Music Awards last Sunday.

"For the first time ever I got to perform w *NSYNC as an out entertainer and was thinking of this man the whole time," Lance posted on Instagram on Wednesday.

'N Sync broke up in 2003 and Lance Bass publicly came out as gay in 2006.

Lance and Michael first started dating in December 2011.

Lance spoke about the engagement on his radio show Dirty Pop from Southern Decadence.
